Ducted Wind Turbine Meshing Problem

  Dear all,
  
  I'm currently working on a ducted wind turbine for a university project where the aim is to evaluate the torque of the turbine inside the duct.
  
  As the first step, I created a rotating domain that includes the turbine and an external domain that includes the duct. Then, I created three booleans: one between the external domain and the rotating domain where I preserved the body, one between the rotating domain and the blades where I didn't preserve the blades and the other between the external domain and the duct where I didn't preserve the duct.
  
  After that, I created an automatic mesh and in the image below you can see the problem:
  
  In the yellow zone (the zone between the rotating domain and the duct) I don't have more than one layer so when I try to run a simulation in Fluent I cannot obtain any results due to the quality of the mesh in that zone.
  
  I tried to use inflation layer or refinement around the duct but the problem seems to not be solved.
  
  I don't know how to attach here my workbench file, so if someone desire to work on it, please just tell me how can I do and I'll do it as soon as possible.
  
  I hope that someone can give me the solution / int to solve this problem.
  
  Thank you very much!

  you will need to give face sizing at that location to get more no. of elements.
